where
1. tADD depends on the operation frequency and may be calculated
using
the following equation
tADD = 1.5 / (fcp) seconds or
tADD = 1.5 /(fosc) seconds
INSTRUCTION DESCRIPTION
Clear Display Instruction
RS R/WB DB7 DB6 DB5 DB4 DB3 DB2 DB1 DB0
00 00000001
This instruction is used to clear the Display Write Space 20H in all DDRAM Addresses. That is, the
character pattern for the Character Code 20H must be a BLANK pattern. It then sets the DDRAM
Address 0 into the Address Counter and reverts the display to its original state (if the display has been
shifted). The display will be cleared and the cursor or blinking will go to the left edge of the display.
If there are 2 lines displayed, the cursor or blinking will go to the first line 's left edge of the display.
Under the Entry Mode, this instruction also sets the I/D to 1 (Increment Mode). The S Bit of the Entry
Mode does not change.
Return Home Instruction
RS R/WB DB7 DB6 DB5 DB4 DB3 DB2 DB1 DB0
00 0000001*
Note: * = Not Relevant
This instruction is used to set the DDRAM Address 0 into the Address Counter and revert the display
to its original status (if the display has been shifted). The DDRAM contents do not change.
The cursor or blinking will go to the left edge of the display. If there are 2 lines displayed, the cursor
or blinking will go to the first line 's left edge of the display.
